Henri St. George settled in Upper Canada in 1847 and established his Glen Lonely estate in Richmond Hill, which contained the lake that bears his name.

After Davies death, the Glen Lonely lands were bought by Schuyler Snively, a World War 1 veteran, who transformed the property into a successful dairy farm, and model country estate.

In 1965 the Snively family negotiated the sale of the property to the Toronto and Region Conservation Authority, with a proviso that they be allowed to reside there until their deaths.

In 1979 the Glen Lonely Farm and Estate was reborn as the Lake St. George Conservation Field Centre, an outdoor education facility that serves many school boards in Toronto and York Region as well as serving as a research and training resource for schools and universities throughout Ontario.

Lake St. George's quiet, expansive forests and meadows, and its pristine kettle lake have become the basis for thousands of students introduction to experiential learning through a variety Ontario curriculum based programs.
